Elementary (ages 5-10)

Passive Pasta

Learn about "passive" cooking through this energy efficient workshop! Participants will make pasta noodles by using hot water and an insulated travel mug, and eat a delicious meal. Water molecules, energy, heat, isolated systems - these are only a few physical concepts introduced in this engaging demonstration!

Cakeraters

Falling space rocks collide with the surface of planets and moons to create impact craters which can be found all over our solar system

Rubens' Tube

Make a flaming tube to explore the physics of waves and acoustics.

The Rubens' Tube should be used with caution and vigilance, especially if used indoors. 

 

Chladni Plates - Speaker

Build a simple Chladni plate using a 6" x 6" metal sheet, a 2 watt speaker, powered with a 20 gain amplifier and phone. Sprinkle sand on the sheet, and play various sound frequencies to reveal the sheet's assortment of resonant vibrational modes. 

Along with the plate demo itself, an amplifier can be made fairly easily with an LM386 op amp. Download instructions for making the amplifier under associated files or can be found here. 

Liquid Nitrogen Ice Cream

Explore the properties of liquid nitrogen while making a tasty treat. This demo is great for chapter socials and smaller outreach events.

Tuning Fork Workshop

Tuning forks are one of the few instruments that resonate with one distinct frequency. Create a workshop with tuning forks with this variety of quick, fun demos ranging from visualizing sound with lasers, to watching energy transfer through pendulums.

Egg Crush

This demonstration dramatically shows how not just the strength of a material, but how it is designed, is important when withstanding forces.

Impulse on Eggs

Participants learn about impulse by building vehicles to drop eggs in.
